Side Return Extension FAQ
How much does a side return extension cost in London? +
Side return extensions in London start from around £2,000 per square metre for a basic build, rising to £2,500 for a higher specification and £3,000 or more for a detailed design. The final figure depends on the size, the glazing and the finishes you choose.
Do I need planning permission for a side return extension? +
Many side return extensions fall under permitted development, so planning permission is not always needed. Larger extensions, homes in conservation areas and most flats will usually need a full planning application. We assess your project and advise which route applies before any work begins.
How long does a side return extension take to build? +
Most side return extensions take between 10 and 16 weeks on site, depending on the size and complexity of the build. The design and planning stage beforehand typically adds a few months, so it is worth starting early.
Will a side return extension take space from my garden? +
No. A side return extension fills the narrow alley of unused land to the side of the house, so it adds width to your kitchen without eating into the main garden. This is one of the main reasons the layout is so popular on London terraces.
What is the difference between a side return and a wraparound extension? +
A side return fills the side alley only, while a wraparound combines the side return with a rear extension for more space. We help you decide which layout gives you the most usable room for your budget.
